Intel Core i5-4400E vs Intel Core i5-4200H vs Intel Core i5-4340M

Intel Core i5-4400E

The Intel Core i5-4400E is a dual-core processor for embedded systems launched in mid-2013. It is based on the Haswell architecture and is manufactured in 22nm. Due to Hyper-Threading, the two cores can handle up to four threads in parallel, leading to better utilization of the CPU. Each core offers a base speed of 2.7 GHz, but can dynamically increase clock rates with Turbo Boost up to 3.3 GHz for 1 active core. The memory controller supports ECC.

Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports, improving the performance per clock by almost 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

The performance of the Core i5-4400E is similar to the consumer model Core i5-4300M with a slighty lower base clock. Therefore, the 4400E should be comparable to the Ivy Bridge based Core i7-3520M.

The integrated graphics card offers 20 Execution Units (EUs), which represents the GT2 version of the Haswell GPU. Technically, the GPU seems similar to the Intel HD Graphics 4600 found on other Core i5 CPUs, but the clock rate of 400 - 1000 MHz is noticeably lower.

The i5-4400E is rated at a TDP of 37 W including the graphics card, memory controller and VRMs.

Intel Core i5-4200H

The Intel Core i5-4200H is a fast dual-core processor for laptops launched in Q4 2013. It is based on the Haswell architecture and is manufactured in 22nm. Due to Hyper-Threading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.8 GHz but can dynamically increase clock rates with Turbo Boost up to 3.4 GHz for 1 active core and 3.3 GHz for 2 active cores.

Architecture

Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Performance

Due to these changes, the performance per clock has been improved by almost 10 percent compared to Ivy Bridge. Therefore, the i5-4200H is slightly faster than the former top model i7-3520M and roughly on par with the Core i5-4330M.

The i5-4200H is rated at a very high TDP of 47 W including the graphics card, memory controller and VRMs. This TDP range is typical of mobile quad-core processors. Therefore, the CPU is suited for laptops 15-inches or greater.

Intel Core i5-4340M

The Intel Core i5-4340M is a fast dual-core processor for laptops launched in Q1 2014. It is based on the Haswell architecture and is manufactured in 22nm. Due to Hyper-Threading, the two cores can handle up to four threads in parallel leading to better utilization of the CPU. Each core offers a base speed of 2.9 GHz but can dynamically increase clock rates with Turbo Boost up to 3.6 GHz for 1 active core or 3.5 GHz for 2 active cores. The 2C Turbo clock has not been confirmed yet.

Architecture

Haswell is the successor to the Ivy Bridge architecture with improvements on both GPU and CPU performance. The CPUs are produced in 22nm and offer an optimized branch prediction as well as additional execution ports, improving the performance per clock by 5 - 10 percent. Furthermore, new features like AVX2 and FMA should increase the performance in future applications.

Performance

Compared to the Core i5-4330M, the 4340M is clocked just 100 MHz higher and therefore only slightly faster. Overall, the performance is almost on par with the Core i7-4600M. Even very demanding software or multitasking will be handled easily.
